Description

Technical Field

[0001] This utility model belongs to the field of automated logistics equipment technology, specifically relating to a high-level pallet stacking and destacking machine. Background Technology

[0002] The core function of a pallet destacking and stacking machine is to separate and stack pallets. This equipment, in conjunction with lifting devices or conveyor systems, can quickly and accurately separate stacked pallets or stack separate pallets together. With the intelligent transformation of the warehousing and logistics industry, the application prospects of pallet destacking and stacking machines will be even broader. In summary, a pallet destacking and stacking machine is an automated device integrating advanced technology and intelligent control. By improving the efficiency of pallet splitting and stacking, it significantly reduces the need for manual operation and optimizes the overall warehousing and logistics process.

[0003] Conventional pallet destacking machines are placed on the ground, with conveyors passing through them. However, empty pallets occupy space, preventing other goods from passing through, necessitating a separate conveyor line. This results in increased space requirements and costs (due to the additional conveyor line and potential lifting and transplanting machines). Therefore, there is an urgent need to design a high-level pallet destacking machine to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-level tray destacking machine to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-level tray destacking and stacking machine, comprising:

[0006] An overhead frame, wherein guide rods are fixed vertically at the four corners of the top of the overhead frame, a connecting rod is fixed at the center of the top of the overhead frame, and frame pins are fixed at both ends of the connecting rod;

[0007] The lifting device includes a base, a column fixed vertically on the base, a slide mounting plate movably connected to one side of the column, and a fork arm fixedly connected to one side of the slide mounting plate. Fork arm pins are fixed on corresponding sides of the fork arm.

[0008] Furthermore, it also includes a conveyor system that runs through the bottom of the overhead frame.

[0009] Furthermore, the conveying device is a chain conveyor or a roller conveyor.

[0010] Furthermore, it also includes empty pallet sets transported by a conveyor, the empty pallet sets comprising several pallets stacked one on top of the other, each side of the pallet having fork holes corresponding to frame pins and fork arm pins.

[0011] Furthermore, both the frame pin and the fork arm pin include a cylinder and a fork, with the fork fixedly connected to the piston rod of the cylinder.

[0012] Furthermore, a slide rail and a rack parallel to the slide rail are fixed to one side of the column in a vertical direction. A lifting motor is fixed to one side of the slide mounting plate. The rotating shaft of the lifting motor extends through the slide mounting plate to the other side, and a gear that meshes with the rack is fixedly installed at the bottom end of the rotating shaft.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] (1) The high-level pallet destabilizer is advanced in design, compact in structure and easy to use. By setting up an overhead frame and lifting device, empty pallet groups can be arranged above the conveyor to ensure that goods can pass through normally. There is no need to occupy space separately for the arrangement of the pallet destabilizer, nor is there a need to set up a separate conveyor line and lifting transplanter, which helps to save equipment costs.

[0015] (2) The high-level pallet destacking machine saves space and is flexible and convenient in the layout of automated warehouse and logistics system equipment. It has a wide range of applications, especially in the fields of small space, compact layout, automatic provision of empty pallets and mother pallets, and highly automated warehouse and automated logistics transportation.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] This utility model provides, for example Figure 1-5 The high-level destacking and stacking machine shown in the figure includes:

[0026] An overhead frame 100 has guide rods 101 fixed vertically at the four corners of its top end, and a connecting rod 102 fixed at the center of its top end. Frame pins 103 are fixed at both ends of the connecting rod 102. When the empty pallet group 400 moves to the top of the overhead frame 100, the frame pins 103 can support the empty pallet group 400, allowing it to be positioned at a higher level without obstructing other goods from passing underneath.

[0027] The lifting device 200 includes a base 201, a column 202 fixed vertically on the base 201, a slide mounting plate 205 movably connected to one side of the column 202, and a fork arm 206 fixedly connected to one side of the slide mounting plate 205. Fork arm pins 207 are fixed on corresponding sides of the fork arm 206. The empty pallet assembly 400 is supported by the fork arm pins 207. The slide mounting plate 205 drives the fork arm 206 to move up and down along the column 202, thereby driving the empty pallet assembly 400 to move vertically.

[0028] For example, see Figure 1 As shown, it also includes a conveying device 300 that runs through the bottom of the overhead frame 100.

[0029] In this technical solution, empty pallet groups 400 can be easily transported from other places to the overhead frame 100 via the conveyor device 300, and then the empty pallet groups 400 can be arranged at a high position via the lifting device 200. Alternatively, the empty pallet groups 400 stacked here can be placed one by one on the conveyor device 300 and transported to other required positions, thereby separating the pallets 401. Furthermore, when the empty pallet groups 400 are arranged at a high position, other goods can be transported via the conveyor device 300 without the need for a separate conveyor line, which helps to save costs.

[0030] For example, see Figure 1 As shown, the conveying device 300 uses a chain conveyor or a roller conveyor.

[0031] In this technical solution, chain conveyors and roller conveyors are common material conveying equipment. Both can realize continuous and automated material conveying, significantly improve production efficiency, reduce manual intervention, and are especially suitable for assembly line operations. Moreover, the basic design is relatively simple, and the core components (chains / rollers, drive devices, idlers, etc.) are standardized, ensuring stable operation and low failure rate.

[0032] For example, see Figure 1 As shown, it also includes an empty pallet group 400 transported by a conveying device 300. The empty pallet group 400 includes several pallets 401 stacked on top of each other. Each side of the pallet 401 is provided with a fork hole 402 corresponding to the frame pin 103 and the fork arm pin 207.

[0033] In this technical solution, by controlling the extension and retraction of the frame pin 103 and the fork arm pin 207, the empty pallet group 400 can be supported by the frame pin 103 or by the fork arm pin 207. When the empty pallet group 400 is supported by the frame pin 103, the fork arm pin 207 can move up and down with the fork arm 206, thereby enabling the frame pin 103 to support the second to last pallet 401 in the empty pallet group 400, and the fork arm pin 207 to support the last pallet 401 in the empty pallet group 400, moving it to the conveying device 300 and conveying it, thus enabling the splitting of the empty pallet group 400. When running in the reverse direction, the pallets 401 can be stacked.

[0034] For example, see Figures 2-5 As shown, both the frame pin 103 and the fork pin 207 include a cylinder and a fork, with the fork fixedly connected to the piston rod of the cylinder.

[0035] In this technical solution, the cylinder drives the fork to extend and retract. When the fork extends into the fork hole 402, the frame pin 103 and the fork arm pin 207 can support the corresponding pallet 401 and all the pallets 401 on top of it. When the fork retracts from the fork hole 402, the corresponding frame pin 103 or fork arm pin 207 can no longer support the pallet 401, thus preventing the frame pin 103 or fork arm pin 207 from interfering with the operation of the pallet 401.

[0036] For example, see Figure 5 As shown, a slide rail 203 and a rack 204 parallel to the slide rail 203 are fixed on one side of the column 202. A lifting motor 208 is fixed on one side of the slide mounting plate 205. The rotating shaft of the lifting motor 208 extends through the slide mounting plate 205 to the other side, and a gear that meshes with the rack 204 is fixedly installed at the bottom end of the rotating shaft.

[0037] In this technical solution, starting the lifting motor 208 can drive the slide mounting plate 205 to move along the rack 204, which in turn can drive the fork arm 206 and the empty pallet assembly 400 supported by the fork arm pin 207 to move in the vertical direction so as to place them in a higher position.

[0038] Working principle: When using this high-level pallet stacking machine, the empty pallet group 400 is first transported to the overhead frame 100 by the conveyor device 300. Then, the fork arm 206, driven by the lifting device 200, descends to the bottom pallet 401 and extends the fork arm pin 207 into the fork hole 402 on the side of the pallet 401. Then, the fork arm 206, driven by the lifting device 200, rises to a suitable position (i.e., the engagement point between the second pallet 401 from the bottom and the frame pin 103). Then, the frame pin 103 extends, and at this time, the bottom pallet 401 descends with the fork arm 206 to the conveyor device 300. Then, the fork arm pin 207 is retracted, and the fork arm 206 is raised. After the fork arm is raised to a certain height, the pallet 401 on the conveyor can start to be transported. The fork arm 206 rises to the frame pin 103 and waits for the next cycle to complete the splitting of the empty pallet group 400. The same process is repeated, and the pallet 401 can be stacked by reversing the operation. This high-level pallet destacking machine features an advanced design, compact structure, and ease of use. By setting up an overhead frame 100 and a lifting device 200, it can arrange empty pallet groups 400 above the conveyor, ensuring that goods can pass through normally. It eliminates the need for separate space for the arrangement of the pallet destacking machine, as well as the need for additional conveyor lines and lifting and transplanting equipment, which helps save equipment costs. In the layout of automated storage and retrieval systems and logistics systems, it has the advantages of saving space and flexible and convenient layout. It has a wide range of applications, especially in the fields of small spaces, compact layouts, automatic provision of empty pallets and mother pallets, and highly automated automated storage and retrieval systems and automated logistics conveying.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
